Notice of Availability of the Barton Springs Salamander Recovery
Plan
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of document availability.
-----------------------------------------------------------------------
SUMMARY: The U.S. Fish and Wildlife Service (Service) announces the
availability of the approved Barton Springs Salamander Recovery Plan
(Recovery Plan). The Barton Springs salamander (Eurycea sosorum) is
known to occur near four spring outlets that collectively make up
Barton Springs in Austin, Texas. Habitat loss and modification from
water quality and water quantity degradation are the primary threats
facing the species. The Recovery Plan outlines the necessary criteria,
objectives, and tasks to reduce these threats and accomplish the goal
of delisting the Barton Springs salamander.
ADDRESSES: A copy of the Recovery Plan may be requested by contacting
the U.S. Fish and Wildlife Service, Austin Ecological Services Field
Office, 10711 Burnet Road, Suite 200, Austin, Texas, 78758. The
Recovery Plan may also be obtained from the Internet at: http://www.fws.gov/endangered/recovery/
.

SUPPLEMENTARY INFORMATION:
Background
The Barton Springs salamander (Eurycea sosorum) was listed as
endangered on May 30, 1997, under authority of the Endangered Species
Act of 1973, as amended (Act) (62 FR 23377). The water that discharges
from Barton Springs is essential to the survival of the salamander. It
originates from the Barton Springs segment of the Edwards Aquifer, a
karst limestone aquifer containing a complex system of caves,
sinkholes, fractures, and faults. The Edwards Aquifer is particularly
vulnerable to contamination and land use changes that degrade the
quality of storm water runoff. The primary threat facing the survival
and recovery of this species is the degradation of water quality and
quantity of water that feeds Barton Springs, as a result of
urbanization over the Barton Springs watershed (including roadway,
residential, commercial, and industrial development). The Recovery Plan
includes information about the species, its habitat, and current
conservation efforts. Further, it provides recovery criteria that, when
reached, will signify that the species has recovered to a point where
it no longer warrants listing as endangered or threatened. Recovery
actions are provided to guide recovery implementation and achieve
recovery criteria.
Reclassification from endangered to threatened (downlisting) will
be considered when the following recovery criteria have been met: (1)
Mechanisms (such as laws, rules, regulations, and cooperative
agreements) are in place to ensure non-degradation of water quality in
the Barton Springs watershed; (2) a plan to avoid, respond to, and
remediate hazardous materials spills within the Barton Springs
watershed is in place with high priority measures implemented to
minimize risks to the Barton Springs salamander to a low level; (3)
measures to ensure that continuous, natural springflows are maintained
at all four spring outlets are in place and succesful; (4) a healthy,
self-sustaining natural population of Barton Springs salamanders is
maintained within its historical range; (5) measures to remove local
threats to the Barton Springs ecosystem have been implemented; (6)
captive populations of Barton Springs salamanders have been established
in secure locations under the direction of a Captive Propagation and
Contingency Plan.
The Recovery Plan proposes delisting of the Barton Springs
salamander when the downlisting criteria have been achieved and the
following additional recovery criteria have been met: (1) Water quality
protection mechanisms are shown to be effective and commitments are in
place to continue protection; (2) measures to implement the
catastrophic spill avoidance, response and remediation plans are
ensured; (3) measures to maintain adequate springflows are shown to be
effective; (4) the Barton Springs salamander population is shown to be
viable and stable or increasing; (5) measures to remove local threats
to the Barton Springs ecosystem are shown to be effective and a
commitment is in place to continue the appropriate management of the
surface habitat; (6) captive breeding is shown to be effective and
reliable and commitments are in place to maintain adequate captive
populations for any needed restoration work.
Due to the Barton Springs salamander's reliance on continuous flow
of clean spring water, many of the high-priority recovery tasks
outlined in the Recovery Plan are designed to ensure adequate water
quality and quantity within the Barton Springs watershed, such as: (1)
Developing and implementing catastrophic spill avoidance, response, and
remediation plans; (2) implementing programs to protect sensitive
environmental features important to salamander habitat or the effective
recharge of clean water such as caves, sinkholes, fissures, springs,
and riparian zones; (3) developing and implementing programs to
identify and correct problems from point and non-point source pollution
discharges; and (4) creating a regional management program that will be
used to ensure the protection of aquifer level and springflows under
normal and drought conditions. Other high-priority recovery actions
include ensuring protection for existing spring habitats and
establishing and maintaining adequate captive breeding populations.
Restoring an endangered or threatened animal or plant to the point
where it is again a secure, self-sustaining member of its ecosystem is
a primary goal of the Service's endangered species program. To help
guide the recovery effort, the Service is working to prepare recovery
plans for most of the listed species native to the United States.
Recovery plans describe actions considered necessary for conservation
of listed species, establish criteria for downlisting or delisting
those species, and estimate time and cost for implementing the recovery
measures needed.
The Act requires the development of recovery plans for listed
species unless such a plan would not promote the conservation of a
particular species. Section 4(f) of the Act, as amended in 1988,
requires that public notice and an opportunity for public review and
comment be provided during recovery plan development. The Service
considers all information presented during a public comment period
prior to approval of each new or revised recovery plan. The Service and
others also take these comments into account in the course of
implementing recovery plans.

Endangered Species Act of 1973, as amended (16 U.S.C. 1531 et seq.).
